【Abstract】 A novel PWM-controlled reactor is developed with its principle structure and control method in this paper, based on the analysis of the principle and the simulation results.Controlled withhigh-frequency PWM, the regulationoftheequivalentinductance of the reactor is continuous and smooth, which gives the SVC system using this reactor excellent characteristics of fast dynamic re- sponse and minimal harmonic.更多还原
